Material Changes vs. Prior Period
- Divestiture of Centuri: The Company completed the sale of all remaining Centuri common stock in September 2025, generating approximately $1.35 billion in net proceeds. This resulted in a $205.0 million net income contribution from discontinued operations in 2025, compared to a loss of $22.2 million in 2024.
- Debt Reduction: Proceeds from the Centuri sale were used to fully repay a $550.0 million term loan and reduce the revolving credit facility balance. As of December 31, 2025, no borrowings were outstanding under the Company's term loan or credit facilities.
- Operating Margin Growth: Natural Gas Distribution operating margin increased by $119.6 million (9.0%) year-over-year. This was driven by updated rates in Arizona and other territories ($95.2 million) and customer growth ($11.5 million), partially offset by higher depreciation and interest expenses.
- Customer Growth: The Company added 37,000 first-time meter sets in 2025, representing a 1.6% growth rate.
Guidance, Outlook, and Risks
- Capital Plan: Management estimates construction expenditures of approximately $6.3 billion for the five-year period ending December 31, 2030. This includes an estimated $1.7 billion investment for the Great Basin 2028 Expansion Project, with an expected in-service date in late 2028.
- Dividends: The Board approved an increase in the quarterly dividend to $0.645 per share for 2026, up from $0.62 in 2025.
- Regulatory Proceedings:
- Arizona: General rate case rates effective March 2025; new rate case filed January 2026.
- California: General rate case filed September 2024; final decision expected Q1 2026 with rates effective April 2026.
- Nevada: General rate case rates effective April 2024; new rate case filed January 2026.
- Material Weakness in Internal Controls: The Company identified a material weakness in internal control over financial reporting related to the assessment of estimated future state apportionment rates following the Centuri deconsolidation. This resulted in the restatement of unaudited quarterly financial information for the second and third quarters of 2025. Management is implementing remediation measures.
- Risks: Key risks include regulatory lag in cost recovery, inflation impacting labor and construction costs, potential pipeline safety regulation changes, and the ability to secure labor and materials for the Great Basin expansion.
Investor Verification Checklist
- Restatement Impact: Verify the specific adjustments made to Q2 and Q3 2025 financial statements regarding state tax apportionment and the classification of long-term debt.
- Centuri Proceeds Usage: Confirm the allocation of the $1.35 billion in Centuri sale proceeds between debt repayment, dividends, and future capital projects.
- Great Basin Expansion: Monitor FERC approval status and binding transportation agreements for the $1.7 billion expansion project scheduled for 2028.
- Rate Case Outcomes: Track the final decisions on pending general rate cases in California and Nevada, which will impact future revenue requirements.
